In this study the nut is manufactured from composite material and provides excellent tribology properties under heavy load conditions.
For this purpose the elastic element is imported into ANSYS database, are specified the materials of the elements, boundary conditions and loads.
On this test rig is studied the screw-nut assembly consisting of special bolt 15, nut 10 and washer 11 (there are several washers of various materials).

Their occurrence presages high demands on the durability of the building materials used.
So far, however, cement binder-based materials are most often used.
This is another important argument for the use of secondary raw materials.

Weaknesses: Absence of cycle counting every month leads to unorganised material stacking and at times difficult to find the material.
There are less numbers of effective labours who handles material carefully without damage.
Imported materials are available at very cheap rates.

But the phosphor is still not the best LED light-emitting materials because light fades, the particles are uniformly poor, life is short.
The quantum dot become the new LED light-emitting materials research focus because it has higher phosphor luminous efficiency,longer life,better color purity.
